ANTISKID DEVICE FOB MOTOR-VEHICLE WHEELS. 4`

My invent-ion relates to for motor vvehicle primary object the Application led A11-gust 11, 1924iI Serial No.A 731,255.

antiskid devices wheels, and has for its provision of an Improved construction of` this character which will be 5 highly eli'icient in use and economical in manufacture.

Another object of my invention isS the provision of a novel character specified,

and useful device of the embodying aiitiskidmembers which are separately movable and which tend under the influenceof centrifugal force during the travelling of the wheel, to

crowd upon one another to.tl ie position best adapted to give a traction grip to the wheel.

Another object is vice of this character,

which is readily attached to the wheel and as readily removed therefrom,

which embodiesfeatures of construction that will facilitate quick repairs and replacement of parts, tionally, requires comparatively little space and which, addifor its storage when removed from the wheel.

Other objects wi ll appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. i The invention will be best understood by reference to the forming a part of which,

accompanying drawings this specification, and in Fig. l is a side elevational view showing my improved device as applied` to a motor y vehicle wheel,

Fig. 2 is a cross section taken on line 2--1-5 of Fig. 1,

Fig. 3 is a detailedview of a cross element illustrating in particularity how the same is connected to the side elements and also yillustrating tatably Fig.

in section the antiskid members rocarried thereby, and 4 shows a detailed view of the' T- shaped members which are attached to the extremities `of the cross elements.

'In referring with particularity tothe embodiment shown in ing, it will be seen elements I upon the tire the accompanying drawthat in the production of a-Wheel'S of a motor vehicle. The side elements 5 and 6 consist of bendable cables, made structed of twisted, closely inlaid strands 9` of steel wire and conwhich in turn are made up of bundles of smaller sizedstrands of each'ofxthe cables snapper device 10.

9. `To one'extremity 5 and 6 .is secured a To the opposite extremthe provision of ay Vdemy improved antiskid device I vemploy side.

5 and 6 for connecting the structure `indicated generall ities of the cables 5 and 6 are secured rrings 11 with which the Snapper devices are adapted to be connected in order to secure vthe ends of the side members together" as `clearly shown in Fig. 1. Y y

For the support of my novel antiskid members transversely of the tire 7 I lemploy cross cables 12 which are equipped at their ladapted to have free axial' movement thereon. The antiskid members 13 are also made with circumferential grooves 15 of concave form 1n cross`section, as clearly shown in Fig. 3. It will be noted that each of the antiskid members 13 is in the form of a disk with a bore extendin diametrica-lly therethrough and whereby tliie dered non-circular in form about the axis of the cable k12. The cables 12 thus serve as axles for the free rotation of said anti-skid members when not in actual contact with the ground and whereby said anti-skid members anti-skid member is ren- The cablesv 12 are also made of are free to move and adjust themselves so.

that they never occupy the same relative positions in contact with the tire for any material length of time, thus avoiding undue wear on one s ot in the tire. However,.when the anti-ski members rest in contact with the ground, the weight o f the automobile rests on them, pressingthem into'the ground and -into lthe tire, thus, due to the non-circular form, reventing free rotation, or roller action, o theanti-skid members on the cables. In this nanner good traction is afforded for the tires and thus skidding and slippin is prevented. For the purpose of detachily connecting the'cross cables 12 to and between the side cables 5 and 6, I securefto each of the extremities of the cross cables end hooks at 16 and consisting of adapted to be crim a body portion l the cross ca le,

and soldered upon the end of and consisting further of a'T-sliaped portion 18 which is 'adapted to be curled and crimped upon the side cable. The cross cables 12 carrying their rotatable antiskid members are thus connected to and between the side cables 5 and 6 at equispaced intervals; and these cross cables are of such length with respect to the transverse curvature of the tire 7 that the antiskid members `13, particularly under centrifugal action.

produced by the rotation of the wheel, will be clear of the periphery of the wheel tread so as to have free rotative and axial movement on the cross cables. Obviously, during the rotation of the vehicle wheel, the cross cables 12 will tend to move outwardly or -at a tangent under centrifugal force, and the antiskid members 13 will tend to crowd upon each other towards the highest oint of the bow or liexure of the cross ca les. Moreover, when the motor vehicle makes a quick lateral turn, the cross cables 12 have a tendency to iiex centrifuglally on the inner side (of the vehicle) of t e circumferential central line 19 of the tire 7, and the antiskid members crowding to the highest point of the exure are adapted to have a traction grip which occurs rincipally on the inner side of said circumierentlal central'line 19 of the tire.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without depart- -ing fromthe spirit of the invention. I,

modiiications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An anti-skid device for tires comprising a flexible mesh arrangement and means for securing the same about the tread `portion of a tire and including transverse axle members extending across the face of the tire; and anti-skid members in the form of disks having peripheral grooves and transverse diametrical bores fitting over said axle members.

2. An anti-skid device for tires comprising a flexible mesh arrangement and means for securing the same about the tread portion of a tire and including transverse axle members extending across the face of the tire; and anti-skid meinbersin the formof discs having transverse diametrical bores tting over said axle members.

In testimony-whereor` I have signed my name to this s eciiication.
